I have also recovered from this by rebooting the backup routing engine.

Hi Kronicklez,

 

This error means that backup RE is not synchronized with master. Usually this is seen after a Junos upgrade, RE switchover or a configuration change.

You can run command "show task replication" multiple times on  the master routing engine and see if any of the protocols is not synchronizing. If the Synchronization Status is not complete for all the protocols, we need to investigate further.

 

 

{master}

user@router>  show task replication

        Stateful Replication: Enabled

        RE mode: Master

 

    Protocol                Synchronization Status

    OSPF                    Complete             

    RIP                     Complete             

    BGP                     Complete             

    MPLS                    Complete             

    LDP                     Complete

Hi rahul,

All my output same with your output. All protocol complete status include additional protocol.

Is there any hidden command that dont need to reboot backup RE?

Thanks and appreciate any suggestion.

Hi Kronicklez,

 

There is no such hidden command.

If the replication status is complete for all the protocols and no recent config/hardware change, junos upgrade, RE switcover was done, this could be a transient issue like backup RE  closing the socket due to miss of keep-alive from master RE.

You can monitor at intervals if the error is seen everytime you issue the command. Then refer the log messages and show log mastership from both the routing engines to find any clue. If everything is fine then it is not urgent to reboot the RE, you can plan for it in any upcoming maintenanace window.

Hi,

RE1 already reboot and it stil not resolve. Even RE0 also already reboot but still same. As per last suggestion from JTAC said need to reboot both RE at same time and it need outage. JTAC said have internal PR for this issue. Can somebody from juniper here can check that PR?

Thanks
